Title: Improvements in and relating to fuel injection pumps
Inventor: SILBERSTEIN HANS
IPC: F02M59/34
Filed: 1957-09-18
Abstract: 839,350. Fuel injection pumps. PETTERS Ltd. Sept. 12, 1958 [Sept. 18, 1957], No. 29360/57. Class 102(1). A fuel injection pump comprises a pump plunger 7 provided with a spill passage 9 controlled by a sleeve 8a connected by a bridge member 13 to a spring loaded piston member 11. A tappet 21 secured to the plunger is provided with ports 23 through which fuel flows from the inlet and is pumped past a non-return valve (not shown) to the spill chamber 3. A needle 20 of an adjustable needle valve 6 is secured to the piston member 11 and controls the leakage of fuel from the spill chamber 3 to the inlet chamber 4. As the pressure in the spill chamber rises, due to increased engine speed, the piston 11 is moved against its spring 12 and moves the sleeves 8a to allow more of the fuel to spill from the injection chamber 10. However movement of the piston 11 also moves the needle 20 to increase the escape of fuel from the spill chamber until a state of balance is reached i.e. the engine runs at a constant speed determined by the setting of the valve 6. Any variation from this speed results in a change of pressure in the spill chamber to vary the position of the sleeves 8a. The extent of movement of the piston 11 in one direction is controlled by a rotatable cam-member 14 which may be adjusted to provide increased fuel for starting.

Abstract: 520,089. Winches. CORRIE & CO., Ltd., J. B., and CORRIE, B. J. B. Oct. 12, 1938, No. 29522. [Class 45] [Also in Groups XXIV and XXX] In winch devices, such as fence wire strainers, in which a ratchet wheel on the winding drum shaft is controlled by a pawl, the pawl has a sliding movement and imparts its stress reaction directly to the frame of the winch. The Figure shows a pawl 42 provided with an elongated medial slot 47 which takes over the drum shaft. A lug 48 on the pawl projects forward to engage the ratchet teeth 38, and a dug 46 projects rearward to lie in a notch 22 in the frame side 24. When the ratchet wheel turns in an anticlockwise direction the teeth 38 raise the pawl by the lug 48, the pawl dropping by gravity as each tooth passes. Pressure by the wheel in the clockwise direction is taken up by the pawl and imparted directly to the face 44 of the notch 22. In another form the notch 22, is located at the bottom of the frame 24, the lug 46 being correspondingly situated. In a further modification, the notch is arranged so that both lugs are in lime, and in a specific form of this modification the pawl is located between the drum and the frame side 24 so that a single lug projects outward to lie in the notch 22 and to engage the ratchet teeth.

IPC: B61L29/28
Filed: 1923-11-24
Abstract: 227,250. Deacon, W. Nov. 24. 1923. Retractive switches. - Electric switches for operating apparatus at cross roads, are actuated by sets of ball or roller supported plates which are sunk in the road surface and are arranged so that the passage of a vehicle approaching the crossing moves the plates in a direction longitudinally of the road. Plates 74, Figs. 5 and 7, disposed in the road surface and supported on rollers 87 are moved longitudinally between the plates 68, 81 upon the passage of a vehicle approaching the crossing. The plates 74 are not operated by a vehicle proceeding away from the crossing. Neighbouring plates 74 carry projection 100. 76 which co-operate with a spring controlled plunger 78 having a contact 91 and an armature 80. The operation of one or more of the plates 74 by vehicle actuates the plunger 78 to break a circuit at the contact 90 and establish a circuit for the holding magnets 95 through the contact 93. Breakage, of the circuit at the contact 90 operates the signalling apparatus at the crossing. The plunger 78 is held in its operated position until the circuit of the magnet 95 is broken by the operation of road mechanism placed at the crossing. Instead of rollers, balls or ball or roller bearings may be employed for supporting the plates. Projections 73 carried by the plate 74 restore the rollers to their initial positions after the passage of the vehicle. A plate 75, attached to the plate 74, overlaps the plates 68, 81 and is provided with an upper non- slipping surface. in a modification, the contact 90, armature 80 and magnet 95 are omitted and the road mechanism is employed for operating a signalling apparatus which has a dash-pot control. Specification 196,719 is referred to. One of the Provisional Specifications also refers to Specification 211,738.

Title: Improved process of making cupriferous zeolitic fungicides
IPC: A01N59/06
Filed: 1936-11-02
Abstract: In the production of dry powdered fungicides for spraying and dusting vegetation, a zeolite is formed from gelling mixtures of sodium silicate and sodium aluminate or aluminium sulphate solutions and a solution of a copper salt such as the sulphate, the reagents being used in such proportions that the zeolite contains non-exchangeable copper in more than equimolecular ratio to the alumina and that the molecular proportion of silica is equal to or greater than that of the alumina and copper oxide taken together.  The copper salt may be added at any time prior to final drying of the gel, and the reaction mixture preferably has a substantially neutral reaction.  The final gel is dried, washed and comminuted to a fine powder, drying being effected preferably in two stages, the partially dried gel being granulated in water, then washed, and drying being completed before grinding.  The copper content of the gel may be increased by adding alkali to the neutral gel and then further copper sulphate.  In the examples the gels may contain per mol. Al2O3 from 1,2 to 10,4 mols. CuO and from 2,83 to 12,5 mols. SiO2.  The Specification as open to inspection under Sect. 91 comprises also the introduction of copper in non-exchangeable form into any zeolite and in any proportion desired.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in process and apparatus for extraction of oils, fats and other soluble constituents from materials containing the same
IPC: C11B1/10
Filed: 1936-11-02
Abstract: <PICT:0484117/III/1> Fats and fatty oils are extracted with <PICT:0484117/III/2> solvents from raw materials containing them, by dividing the powdered raw material into a series of superposed zones a ... k, Fig. 1, in an extraction column 1, by means of transverse flat or dished partitions 3 mounted on a central rotatable axis 4. Each partition 3 is provided with an aperture 31, out of vertical registration with the apertures in adjacent discs, whereby the raw material passes downwards in a spiral path around the axis.  The main body of the material is held against rotation by a fixed vertical baffle 5 in each compartment, which acts as a dam over which freshly exposed material continuously overflows. Raw material is fed in at the top of the column through a hopper 7 and a solvent such as gasoline is pumped in at the bottom at 16. Counter-current extraction is effected without packing of the raw material, and the miscella passes through a pipe 18 to a still. Exhausted material passes from the base of the column into an expansion chamber 8 where it is compressed by a screw conveyer 10 against a spring loaded valve 15, to form a plug of material impervious to solvent.  The compressed material then falls into a steam jacketed drier 13, from which solvent vapours pass through pipe 12f to a condenser.  The material is then conveyed by a screw 121 to a tank 20 where final traces of solvent are removed by steam jets 20d.  Steam and solvent vapours pass to a condenser, and exhausted material is discharged through a pipe 20g.  The rate at which extraction is effected is controlled by the discharge screw 121.  The solvent may be heated as it rises in the column in heaters 50, 51.  Where the solvent is heavier than the raw material, the extraction column is arranged with the solvent inlet, and drier for exhausted material at the top of the column, and raw material is charged into the bottom of the column.  A modified form of mechanism for forming the raw material into a solvent-impervious plug is shown in Fig. 11, in which the sides of the tank 8 converge into a trough 8b, in which is mounted a perforated screw conveyer 101.  Exhausted material is thereby conveyed through an opening 1a into a cylindrical conduit 12 of larger diameter than the opening 1a.  A short screw 12a compacts the material against the spring-pressed conical valve 15 to form a plug, impervious to solvent.  Creeping of solvent along the shaft is prevented by a tapering at 11d.

[Also in Group XXII] The ends only or the entire length of a hollow flexible coiled wire shaft have or has a square, triangular, hexagonal, rectangular or other polygonal internal cross-section for slidably receiving complementary terminals 19, 22 on the driving and driven shafts 18, 24. In Figs. 9 and 10 (not shown), the hollow shaft is wound from rectangular or square wire on a square-sectioned expanding mandrel the stranding being continuous with oppositely handed successive layers 14 ... 17. Where only the ends have a square section a circular sectioned shaft is wound in a continuous length on an automatic spring-coiling machine and spaced square portions to form individual shaft ends are then cold-pressed on an hydraulic press having jaws which permit a gradual change from the circular to square shape. The shaft is then cut into lengths through the centres of the square ports. The ends of the shaft are spot-welded (Fig. 8, not shown), to secure the individual coils and surface ground. The drive connection may be strengthened by forming the shaft 24 with an external socket 23 in addition to the internal plug 22, which latter is formed on a square head 20 pinned in a complementary socket in the shaft port 24.
